I think it's nice to have some idea of the words, but you certainly don't have to identify every word they're singing the moment they sing them. Nickel- that sounds lovely; well done for managing it despite the snow!
I went along to see the choir (and my eldest- the 8 year old) singing Britten's St. Nicholas, which was fab, especially with all the snow whirling past the church windows. They managed the whole programme (had a paid strings orchestra too) with some other bits in the first half, but no time for an interval so we could get home before we got snowed in!
I do like a bit of Britten, despite it being desperately un-trendy. I was a mouse in Noyes Fludde in church as a very small child (maybe 3 or 4?), and can still remember creeping up the aisle singing, 'Kyrie, kyrie, kyrie eleison' :)
We didn't manage to get her to church in time to sing yesterday morning, though. Choir master not too impressed, but heck, I had four to get out of the house and it took ages and ages and ages to get them all salopetted/snow booted/gloved/hatted etc. so we arrived in the first hymn.
